Geoengineering, i.e. tinkering with the climate to stop the rising tides of climate change, is a provocative and frankly still kinda crazy idea. Two long-awaited reports from the National Academy of Sciences (NAS) out today have some pretty harsh words about geoengineering. »2/10/15 4:10pm 2/10/15 4:10pm

This is the microbes' world—we just live in it. Throughout the history of Earth, microbes have radically reshaped life on the planet, from creating the very air we breath to wiping out almost all life on Earth. Don't underestimate the power of tiny, tiny microbes populating the Earth trillions of times over. »4/07/14 12:00pm 4/07/14 12:00pm

Regardless of whether or not geoengineering actually does anything positive about climate change, it'll probably have some unintended consequences. Take, for example, this theory that geoengineering will bleach the sky. »6/04/12 7:40pm 6/04/12 7:40pm

Here's the plan: A giant garden hose 12.4 miles long, tethered to a ship and attached to a 650-foot (about two football fields) balloon, which will pump out hundreds of tons of chemical particles into the stratosphere to mimic a volcano. »9/03/11 10:00am 9/03/11 10:00am

A physicist at Harvard has an idea for fighting climate change that's radical in every sense of the word. He wants to pump massive amounts of microbubbles into the world's oceans, increasing their reflectivity and cooling their waters. »3/27/10 4:30pm 3/27/10 4:30pm

While humans have unintentionally been altering Earth's climate for centuries, some scientists have begun to study how to intentionally hack the globe to cool the overheated planet. »3/25/10 1:20pm 3/25/10 1:20pm
